    For those who for some reason (for example bugs in newer versions...) cannot upgrade, there is a workaround that worked in my case: after clicking apply and the UI getting messed up, hit undo (ctrl+z), and then apply again. The second time it doesn't get messed up.

    Please reopen. This is still not fixed in Unity 2017.3.1f1. It has seriously affected our work.

    It is quite frustrating, are there any work arounds?
